3.4 System Settings
Basic system settings include the server name, date, time, and language settings.
•
Server Name
You must assign a unique name for your GNS-8000A for ease of identification
within the local network. The server name can accommodate as much as 14
characters, which can be a combination of letters (A-Z or a-z), numbers (0-9)
and hyphens (-). The server will not accept name containing blank spaces,
period (.), or names with only numbers. The LCD display will show the
current server name.
Next, you must configure your GNS-8000A to the workgroup. The workgroup
represents a basic computer group within the Microsoft Network. Files are
normally shared within the group. Workgroups can accommodate as much as
15 characters but must exclude the following characters:
;:"<>*+=\|?,[]/
The first character cannot be a period (.). For ease of management and
usage, please set your GNS-8000A and attached computer(s) in the same

creating or displaying files and directories. Select the correct language
settings to avoid the following problems:
1.
2.
•
Inability to create files or directories with special wording.
Inability to display files or directories name with special wording.
View System Settings
You can view all the current system settings such as server name and
workgroup from this page.
3.5 Network Settings
The network settings include TCP/IP configuration and network service settings.
•
TCP/IP Configuration
According to your local network, you can choose the following two methods
to configure the TCP/IP settings:
Obtain IP address settings automatically via DHCP
If your network supports DHCP, the GNS-8000A will automatically use
the DHCP protocol to retrieve the IP (Internet Protocol) address and
related information.
Use static IP address
Use the user defined IP address settings.
-
Fixed IP Address
The IP address is a 32-bit digit code used to differentiate each single
entity on a network. The IP address is separated into 4 groups of
eight bits separated by dots: 192.168.0.1.
13
-
Subnet Mask
The subnet mask is used to define computer within the same local
network. It is a 32-bits digit code: 255.xxx.xxx.xxx.
-
Default Gateway
The gateway is generally referred as an interchange point that
connects two networks, such as LAN and WAN. If you do not need to
configure gateway address, set it as 0.0.0.0.
-
Enable DHCP Server
Once the DHCP server’s dynamic address allocation function is
activated it will automatically assign dynamic addresses to any
computer in the network that is configured to automatically obtain IP
addresses.
Note: Only one DHCP server may be activated at any time in a
network to avoid causing conflicts in communication.
-
Configuration of Network Interfaces
The system supports multiple network interfaces that enable you to
perform Fail Over and Load Balance functions. Fail over ensures server
availability to the network. If the primary port is disconnected due to a
hardware or cable problem, the secondary port will replace its network
identity. If the failed port resumes the network connection, it will also
resume the role as the primary interface.
When using Fail Over or Load Balance, you can select to connect the
network cable to an exchange device that supports trucking function and
then enable the function.
•
Microsoft Networking
Users using the GNS-8000A on the Microsoft Windows operating systems must
start Microsoft Network Services.
If the local network has a WINS server installed, please specify the IP
address. The GNS-8000A will automatically register its name and IP address
with the WINS service. Or you can enable your GNS-8000A as the WINS
server for your network.
•
Apple Networking
Users using the GNS-8000A on Apple’s Mac operating systems must enable
AppleTalk network support.
If your AppleTalk network uses extended networks, and is assigned with
multiple zones, please assign a zone name to the GNS-8000A. If you do not
want to assign a network zone, please enter an asterisk (*). Asterisk (*) is
the default setting.
14
•
NFS Service
Users using GNS-8000A on Unix/Linux operating system computer or server
must start Unix/Linux NFS service. The GNS-8000A supports NFS version
2.0/3.0. To correctly use the NFS service, you must assign a User’s UID and IP
address. Please select User Management · Users · NFS Settings to start the
setup.
•
NetWare Service
If you wish to use NetWare to access the GNS-8000A, you must activate the
NetWare service. The GNS-8000A will then operate in a manner similar to a
Novell NetWare 3.12 file server.
•
Web Service
Other than standard OS support, you have the choice to use a web browser to
access your files on the GNS-8000A. If your GNS-8000A is connected to the
Internet and uses a valid IP address, the GNS-8000A allows you to access your
files using a web browser from anywhere in the world.
•
FTP Service
If you wish to download files from or upload files to your GNS-8000A by using file
transfer protocol (FTP), you must first activate the FTP service.
•
View Network Settings
You can view all the current system settings such as server name and workgroup
from this page.
3.6 Disk Configuration
Depending on the models, the GNS-8000A can accommodate a maximum of eight
disks. The Disk Volume can be configured according to your needs.
•
Single Disk
You can choose to use a stand-alone disk. However, if the disk is damaged,
all data will be lost.
•
RAID 5 Disk Volume
Three or more hard disks can be teamed up to form a large-capacity RAID 5
disk group. This system will distribute and store data among its various
member disks as it is received. At the same time it uses an amount of space
roughly equivalent to a whole disk to store reference numbers with the same
elements. Should one of the disks in the group suffer some kind of damage,
you can shut down the computer and install a new disk, and the system will
restore the data on the new disk using the reference number. In addition, if
you have a system with four disks but use only three in your RAID 5 group,
the fourth will serve as a backup disk. If one of the three disks is damaged
the system will automatically start using the spare disk without powering
down and changing the affected disk. Generally speaking, the capacity of a
15
RAID 5 disk group is one disk’s worth of space less than the total rated
capacity of the group.
Note: RAID 5 may be used only with equipment that has three or more
disks.
•
RAID 1 Mirroring Disk Volume
Mirroring Disk protects your data by automatically backing up the contents of
one disk onto the second disk of a mirrored pair. This protects your data if
one of the disks fails. Unfortunately, the storing capacity is equal to a single
disk, as the second drive is used to automatically back up the first. Mirroring
Disk is suitable for personal or corporate use to store important data.
•
RAID 0 Striping Disk Volume
Striping disk combines two or more disks into one larger disk. It offers the
fastest disk access but it does not have any protection of your data if the
striped array fails. The disk capacity equals the number of disks in the array
times the size of the smallest disk. Striping disk is usually used to maximize
your disk capacity or for fast disk access but not for storing important data.
•
Linear Disk Volume
You can combine two or more disks into one larger disk. During file saving,
the files are saved on physical disks sequentially but do not have a disk
failure file protection function. The overall capacity of linear disks is the sum
of all disks. Linear disks are generally used for storing large data and are not
appropriate to use for file protection of important data.
By factory default, the GNS-8000A has been pre-set into one large disk. If
you wish to use other disk configurations, the settings can be changed during
the first Quick Configuration access. Furthermore, to increase the hard disk
life, the hard disk will go to standby mode if there is no access within 30
minutes. If any data access happens while the hard disk is in stand-by mode,
it will take 3 or 5 seconds for the hard disk to return to normal mode. You
can select System Tools · Hardware Settings to change the setting.
You can also perform the following disk administration:
Create Disk Volume
Delete Disk Volume
Examine Disk Volume
Format Disk Volume
View Disk & Volume Status
In addition to the above functions, users can also perform snapshot taking in
Snapshot Settings of System Tools. This function enables users to take a
real-time and dynamic replication of the snapshot according to the disk
volume at a certain point of time. The data contained in the snapshot is the
same as the previously copied network hard disk drives. The content in the
snapshot will not be affected even when changing the content of the disk
volume. If an original data is damaged, it can be restored from the snapshot
image.
16
3.7 User Management
The GNS-8000A can share its files with multiple users. It is important to plan and
organize users and user groups’ accessibility to ease the administration work.
•
Users
The factory default settings include the following users:
Administrator
By default, the administrator is a member of the administrators group and
has access to the system administration. You cannot delete the user
Administrator.
Guest
When you use a non-registered user name to login, the server recognizes it
as a Guest and will allow limited access. A guest does not belong to any user
group. You cannot delete the user Guest or create a password.
Anonymous
When you connect to the server by FTP service, you can use the name to
login as a guest. You cannot delete this user or change its password.
You can create a new user according to your needs. The following
information is required to create a new user:
•
User Name
The user name must not exceed 32 characters. It is case insensitive and it
can contain double-byte characters. (Such as Chinese, Japanese, and Korean)
But it cannot contain any of the characters below:
" / \ [ ] : ; | = , + * ? < >` '
•
Password
The password must not exceed 16 characters. Due to security concerns, the
password must be at least 6 characters. Try to avoid using codes that are
easily decipherable.
You can perform the following settings for users:
•
•
•
•
•
•
•
•
Create User
Create Multiple Users
Create Private Network Share
Assign User Groups
NFS Settings
Quota Settings
Delete User
User Groups
To administer access rights, you can create user groups. User groups are a
collection of users with the same access rights to files or folders. By factory
default, the server contains the following pre-defined user groups:
17
Administrators
All members of the administrator group have the rights to perform system
management. You cannot delete the administrator group.
Everyone
All registered users belongs to everyone group. You cannot delete the user
groups, “Everyone” or delete any of its users.
You can manage user groups with the following options:
•
•
•
•
Create User Groups
Create Private Network Share
Assign Users
Delete User Groups
User groups name must not exceed 256 characters. It is case insensitive and
it can contain double-byte characters such as Chinese, Japanese, and Korean.
But it cannot contain any of the characters below:
" / \ [ ] : ; | = , + * ? < >` '
To properly manage security, it is very important to manage users and user
groups. You may set the share access parameters of each user or user group
accordingly.
•
PDC Authentication Settings
If you have a Windows PDC (Primary Domain Controller) server to handle the
domain security in your network, you don’t need to re-enter all the users and
groups with the GNS-8000A. You can simply enable the PDC authentication
feature; the GNS-8000A will connect with the NT domain and get all the
information of the domain users and groups automatically.
To enable PDC authentication, you must enter the domain name as well as
the user name and password already established in this domain. The GNS8000A will use the user name and password to log in to the NT domain and
retrieve user and group information. Once you have configured the GNS8000A to use PDC authentication, all NT domain users and groups will appear
in lists of users and groups for which you can define access rights.
Note: NetWare users cannot be authenticated via the PDC server. To
properly authenticate NetWare users, please go to User Management ·
Users · Change Password page and type the password for that user
manually.
•
AD Authentication Settings
If you have a Windows AD (Active Directory) server to handle the domain
security in your network, you do not need to re-enter all the users and
groups with Disk On-line Server. You can simply enable the AD
authentication feature; Disk On-line Server will connect with the AD domain
and get all the information of the domain users and groups automatically.
To enable AD authentication, you must enter the domain name as well as the
administrator’s user name and password already established in this domain.
Disk On-line Server will use the user name and password to log in to the AD
18
domain and retrieve user and group information. Once you have configured
Disk On-line Server to use AD authentication, all AD domain users and groups
will appear in lists of users and groups for which you can define access rights.
Note: NetWare users cannot be authenticated via PDC and AD servers. To
properly authenticate NetWare users, please go to User Management ·
Users · Change Password page and type the password for that user
manually.
For more information, please refer to Appendix E, Active Directory User Guide
•
Quota
The amount of space given out to all users in the system can be limited in
order to manage and allocate it efficiently. Once these restrictions are in
place, users will be prevented from obtaining more space once they have
reached their limit. This prevents monopolizing of a large amount of disk
space by a small group of users. No limitations are set on the system when it
leaves the factory.
19
3.8 Network Share Management
The primary purpose of network storage is file sharing. In a standard operation
environment, you can create different network share folders for various types of
files, or provide different file access rights to users or user groups. By factory
default, a “public” share folder is created. The share folder gives full access to all
users or guests.
Administer network shares with the following:
•
•
•
•
Create a Network Share
Change the name, path and comment of a network share
Set access right for a network share
Remove a network share
You can create new network shares according to your needs.
network share the following parameters must be set:
•
While creating a
Network Share Name
The network share name must not exceed 32 characters. It cannot contain
double-byte characters (such as Chinese, Japanese, and Korean) as well as
the characters listed below:
". +=/\:|*?<>;[]%
•
Disk Volume
The network share will be created under the specified disk volume.
•
Path
All data are stored under the assigned path onto the disk volume. You can
select Specify Path Automatically to allow the server to automatically
create a new path on the disk volume to store the network share files. Or
you can assign a specific path for the share folder. The manually assigned
path cannot exceed 256 characters and cannot contain the characters listed
below:
"\:|*?<>;`'
•
Comment
The Comment field allows a brief description of the share folder to help
users identify its purpose in a network neighborhood window. The comment
cannot exceed 128 characters.
Once the network share is created, you can start assigning access rights to
users or user groups:
•
Full Access
Full access allows the user or user group to read, write, create, or remove all
files and directories in the network share.
20
•
Read Only
Reads files only in the network share but denies functions to write, create or
delete files or directories.
•
Deny Access
Denies all files access on the network share.
3.9 System Tools
The following system tools allow optimized maintenance or management of your
GNS-8000A:
•
SNMP Settings
In order to use Simple Network Management Protocol (SNMP) to manage the
GNS-8000A's network components, the SNMP service must be started.

system will shut down automatically by probing the power status of the
21
connected UPS unit. You can also set a shutdown timer to turn off the
system automatically after it detects the AC power failure. In general, the
UPS can keep supplying the power for the system for about 5 to 10 minutes.
But this depends on the maximum load of the UPS and the number of the
loads connected to it.
The UPS is supported by the following two ways:
1. via a serial port interface (only for models with serial port)
2. via SNMP network management protocol
If the UPS you used is not supported, please contact technical support or visit
our web site for updated news.

Tape Backup (Applicable for models with SCSI port only)
The tape backup tools allow you to perform the backup or restore jobs using
a tape drive with ease. In principal, there are two different types of backups:
Full Backup or Incremental Backup. Full backup will back up all the files in the
backup source. However, the incremental backup will only back up any
modified or new files after last backup.
-
Backup Now
To back up the files to the tape right away, you can run an immediate
backup job.
-
Restore
To restore from the previously backup tape, you can perform the restore
operation.
-
Scheduled Jobs
You can schedule a backup job to be executed automatically at any later
time periodically.
-
Tools
There are several useful tape functions to operate on the tape drive. For
example, you can rewind, eject or erase the tape here.

backed up to a particular remote folder when the job is executed.
-
Real-time
This function makes real-time remote replication possible. Once the local
client and the remote server are set up probably, files copied to the
specific local folders will be replicated immediately to the corresponding
remote folder. The replicating process has been optimized. Therefore,
only different part of a file is copied. When a local file is removed, the file
on the destination folder will also be removed.
-
Server Setup
A real-time remote replication server can accept specific client connections,
and makes a duplicate of the client data. To make this server a real-time
remote replication server, you have to set up the server first.
Note:
1. Before using this function, make sure Microsoft network service of
remote GNS-8000A has been enabled. Check that the replication path
is correct and the user account is authorized for accessing the remote
server.

Snapshot enables users to create a copy of disk volume instantaneously as a
backup source. Taking a snapshot takes only a few seconds and there is no need
to stop the file service in the process. The creation of snapshot will not modify
the disk volume while any changes made to the disk volume will not affect any
formerly taken snapshots.
Each snapshot records disk volume at a certain point of time. Snapshot settings
can perform snapshot taking automatically for the system. In case of system
malfunction like deleting files by mistake or being infected with virus, users can
make use of snapshots created to restore the files. In addition to backup and
restoration of disk volume, users can also schedule snapshot taking and create
multiple snapshots for data restoration.
